At which age is it still normal for an infant to have genu varum?

A: One and a half years

The correct answer is A. Physiologic genu varum is seen in the first year and a half and it progresses to neutral at 2 years of age. At 3 years the further progression leads to a moderate genu valgum and finally reaches the physiologic genu valgum of 5-10° around the age of 7. This is important to know in order to be able to distinguish a normal finding from Blount’s disease which requires early treatment.

B: Three years

C: Seven years
